I BERTH, a citizen of the United States, resid ing at Cleveland, in the county of Cuyahoga 'WINDSHIELD- C EANER;

Original application filed January 25, 1919, Serial No. 279,143. Divided and this application filed August 2?, 1921, Serial No. 496,129. RenewedAug'ust 15,1922. Serial 1%. 592,072. I

TOJaZZ whom it may cance m i Be it known that I, WILLIAM M. For.-

and State of Ohio,- have invented certain new and useful lmproveme'nts in Windshield Cleaners, of, whlch the following is a specification.

This invention relates to windshield cleaners, and more particularly to a windshield cleaner adapted to be operated by a reciprocating piston. The present application is, a division of my copending application Serial N0.f273,143, filed January 25, 1919. In .the said application, I have disclosed a motor operated windshield cleaner comprising a cylinder andpiston adapted to be connected to the intake manifold of the engine to be operated by the suction within the engine to alternately place the opposite ends of the cylinder in communication with the manifold and reciprocate the iston. In the said application I have broa y claimed the operation of a windshield cleaning element by the reciprocation of the piston.

The present application relates to oscillation of the cleaner element by the reciprocation of the piston. The cylinder containing the piston is adapted to be connected to the intake manifold to cause reciprocation of the piston and means are provided for converting the reciprocating movement of the piston to an oscillating movement of the cleaner element, whereby the cleaner element is swung back and forth in an arc of a circle over the windshield to remove water,

. mist, or other obstructingmatter therefrom.

In, the 'acc'om anying drawings, I. have shown one embo iment of the invention. In

numeral 1 designates a windshield f formedlof suitable 'materialand' rovided' witha-top'2. The frame-is adapte to hold'--.- I v F It. is to be understood that the form of {the invention herewith shown and described this showing:

Figure'l is a front elevation of a w ndshield s howingthe invention applied,

Figure 2 is a vertical sectional view throughthe piston .rod,- and,

Figure 3 is a similar view throughifihw cylinder: l

Referring to the drawings, theireference a windshield t3 ,formedof glassor other transparentwmaterialr .The windshield I cleaner is secured to the frame by means of a U'- shaped.:br'ac ket 4:. One; ofthearms-di' the bracket is provided with a pad of cushioning material 5 adapted-to engage the windshield, the other arm being provided with a set screw 6 by.means of whichv the bracket is. retained in position. One arm of the bracketis provided with av pair of lugs 7 adapted to engage a portion of cylinder 8,.forming the motor of the windshield cleaner. The inner end of the cylinder is provided with a head, 9 arranged therein in any suitable manner and having a substantially U-shaped guide 10 extending outrod is provided with a rack 16. formed thereon and adapted to mesh with a pinion 17 mounted on a shaft 18 carried by a pair of arms 19 extending downwardly from the U-shaped guide. This shaft is adapted to carry a cleaner rod 20 having a cleaner'elementZl arranged thereon adapted to contact with the windshield. The cleaner rod 20 may be made of suitable resilient material to retain the cleaner" element in engagement with the windshield. The cleaner element may be provided with a contacting strip 22 of rubber or other yielding material. 1

In, operation, the valve 12' isalternately opened and closed by suitable means to create suction in the end of the cylinder and cause the piston to be moved against the acand normal pressure establishedin thefcylj inder, the tension of the spring moves the piston in the opposite direction. The re-- ciprocation ofthe piston causes thecleaner element to be; oscillated due to the rack 16 and pinion '17,.

is to be taken as a preferred :example'of the tion of the spring. When the valye is closed, I

.sa me andthat various changes inthe shape size, and arrangement of parts may be re sorted to without departing from the spirit of'the invention or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. In a windshield cleaner, a cylinder, a bracket on which said cylinder is mounted, said bracket being adapted to be secured to a windshield frame, a piston mounted in said cylinder, said cylinder being connected to a source of suction to move said piston from a point adjacent one end of the cylinder to a point adjacent the opposite end the cylinder, a cleaner shaft, a cleaner element connected to said shaft and adapted to contact with the windshield, and means for oscillating the cleaner shaft by the movement of the piston.

2. In a windshield cleaner, a substantially air-tight casing, a bracket secured to said casing, said bracket being adapted to engage a windshield frame, an actuating member mounted in said casing, said casing being connected to a source of suction to move mes es a piston mounted in said cylinder, said cylinder being connected to a source of suction, to move said piston from a point adjacent one end of the cylinder to a point adjacent the opposite end, a control valve arranged in said connection, a piston rod secured to the piston, a rack formed thereon, a cleaner shaft arranged adjacent the piston rod, a cleaner element connected to said shaft and adapted to engage the windshield, and a pinion mounted on said shaft and meshing with said rack to oscillate the cleaner shaft by the movement of the piston;

4. In a windshield cleaner, a substantially air-tight casing, said casing being adapted to be secured in operative position adjacent a windshield, an actuating member mounted in said casing, said casing being connected to a source of'difi'erential pressure to move said actuating member from one position within the casing to a second position, a cleaner shaft, a cleaner element connected to said shaft and adapted to contact with.

the windshield, and means for oscillating the cleaner shaft by the movement of tuating member.

In testimony whereof I afix my signature in presence of two witnesses.
